Are you having problems with your feet? I know that the shoes we wear really have a lot of effect on our feet. I got into flats & birkenstocks years ago when I blew out my ACL in my knee playing racquettball. The instability in my knee had a great influence on the shoes I was able to wear.

I assume that since you had x-rays done that you are having serious issues.......but I heard from people here in KY that back in the old days, they x-rayed feet at the shoe stores never heard of such a thing in California
